I'm really pulling for Thune in SD and Coors in CO. If we can only have two of those races, those are the two to get I think. I really think that the pro-RKBA side can do better than just two seats gained though.
Half of those Senate candidates are running in states with a strong pro-RKBA heritage against candidates who are clearly anti-gun. There are a lot of gun owners that need to get out and show the pollsters that the races aren't nearly as close as they are shown here.
Right now we have six Senate races (South Dakota, South Carolina, North Carolina, Florida, Colorado, Louisiana) where a pro-ban grabber is running against an anti-ban candidate. Every one of those races is tied or within the margin of error. Just playing the 50-50 odds, we should pick up 2-3 pro-gun votes in the Senate. If gun owners get out and get mobilized, we can push that over to the 3-4 or even the 4-5 range. Hell, there isn't any real reason we can't win all six since they are all up for grabs.
